Spectacle frames known" as the semi-rimless frame having a temple supporting arm or are following the top of the lenses and to the? rear thereof and secured to the lensesonly on the nasalsides, thereof have become-extremely popular in the last two years. In these spectacles the frame arcs are practically invisible These spectacles, however, do not look well unless; the tops of their: lenses are shapedtd substantially' follow the top fine ofthej eye socket; It is therefore apiir'i'cipal' object of this'i'nventionto fifovide means by which this may" be' done inan' economical way for persons having different facialcharacteristicsiand so that these" spectacles may be assembled, adjusted and fitted with; the least 063E125 the" dispensing Optician; and tlie stock or parts that have to" be carried by the Optician cut down to a-miniifium' to save:1aege' investmei1ts.-

Referring to the drawings" which cori'spond ing parts are incliceized:by'correspondingreference characters throughout:

The lenses lhavethe usualfinishe'd optical surfaces on=their two-faces. Theyare heldin spaced alignment by abridgeimember. 2 to which aresecured the lens'straps- 3.,i'which are-secured to the lenses by screws, solder or other means usual in in temple connections at 8 to which the temples 9 are pivoted.

The relationship of the lenses [arid the arcs 1 to the eye when in place of use and to the brows and eye sockets is shown in Figs. III and IV. The connection 3| for the lens strap'3 is located sub-' stantially on a horizontal line II] passing through the center of the pupil of the eye, and the top line of the lenses I and the line of the arcs I. follow substantially the line of the top of the eye sockets. This positioning of the lenses'with respect to the eyes and the eye sockets is of importance in this invention from the standpoints of standardizing the shapes of the lenses, thelengths of the arcs I, the appearance of the device on the face when in use and for facility in assembling, adjusting and fitting the parts to accommodate varying facial characteristics and reducing the stock of parts necessary for the prescription assembler and fitter to carry. This will be further explained in the description of Figs. V and VI.

The characteristics of the shape of the lenses I are shown in Fig. V. It will be noted that the top line of the lenses I comprises a series of arcs tangentially blended together to produce a continuous line closely approximating the lineof the top of the eye sockets. These arcs are struck about a plurality of centers forming radii of different lengths. The positions of the centers of these radii and the lengths thereof are located and made to insure this continuous top line closely following the line of the top of the eye sockets. Startin from the nasal side of the lenses the arcs are as follows: The first struck about the center I I with the radius I2, then the second with center at I3 and radius 25, then at center 26,- radius 21, then at'center 28 and radius 29, then at center I9 and radius 20, then at center 2L and radius 22, and then at center 23 and radius '24. All these arcs are blended smoothly on the top lineof the lenses. The lens connection position is located substantially on the horizontal line II] passing through the center of the eye when the lenses are in place on the face. This is on the nasal side of the lenses as indicated at 3|. The nasal-sides of" all the lenses I are of the same shape and contour regardless of size, and the connecting position 3|. is the same for all lenses regardless of size. These features will be further pointed out in the descriptionofFig VI. W

The shapes of the lenses I, their sizes, and the lengths of the arcs 'I are standardized as shown in Fig. VI. In the lower half of Fig. VI is shown a series of five lenses I superimposed one over the other. It will be noted that the lensconnecting point 3| is the same for all the lensesof the series, and that the shape or contour of the nasal edges is the same for all the lenses of the series. The'heights above'the horizontal line I0, indicated by the numerals I4,I5, I6, I! and I8 are progressively greater from the line 'IIl upwardly. -'The lenses are progressively wider toward the temple sides, and the depths below the line I0 are progressively greater. It will be noted that the top, temporal and bottom edges are substantially parallel with each other.

In the top half of Fig. VI is indicated a series of arc arms I. These arms are progressively larger as indicated by the lettersA, B, C, D, and E. The length of each of these arms is" made to correspond with the length of the top edge of its corresponding lens.

The standardization of these lens shapes and are arms in a graded series is very important in this invention as it provides many valuable advantages. It simplifies greatly the assembly of the parts for a desired prescription and reduces to a minimum the stock of parts that have to be carried. It standardizes the position of the lens connecting point, the'shape of the nasal edges of the lenses Where they have to fit the nose, and it provides a stock of parts that may be readily assembled to fit the facial characteristics of different patients through the usual practical range of such requirements. I

The procedure of shaping the lenses I is as follows: These lenses are first marked to approximate shape and cut to that shape by a diamond cutter. The edges are then edged and smoothed on a lens edging machine having an edging stone and a cam former which regulates the shape of the lens as it is being edged. I This former is approximately of the shape and size of the top lens of the series indicated in Fig. VI. The cam shoe for the former on the edging'machine may be set by a screw attachment so that the various heights and widths of the lenses of the series may be obtained by use of the single former. The former shoe adjuster is provided with a scale so that it may be set to obtain any desired unit of the series of lenses.

The spectacle is assembled by shaping the lenses to theshape of the desired unit of the series. The corresponding arc arms I are selected and soldered to the bridge, guard arm and lens strap unit known in the art as the center. The lenses are secured. at the points 3| by the lens straps and the temples are pivotally connected to the arc arms I. The spectacle is adjusted and fitted to the face by bending the parts of the center, the arcs I and the temples 9 with opticians pliers.

While the nasal sides and top edges of the lenses are standardized as to shape or contour, the temple sides and lower edges of the lenses may be varied to suit individual tastes, as indicated in Figs. VII to XII inclusive. Of course, where these two sides are varied a former having the desired contour will have to be used on the edging machine. It will b noted in Figs. VII to XII inclusive that thetop edges indicated by the lineand arrow heads and marked 30 ar of the same contour shape to follow the line of the top of the eye socket. The nasal edges of the lenses above the lens connecting point 3| are also alike, and the connecting point 3| is the same for all lenses.

This shaping of the lenses I and the standardization of the top edges, the lens connecting point 3I and the lengths of the arcs greatly facilitate the assembly of these spectacles, enhance their appearance and provide a maximum of economy and, saving in labor to the prescription dispenser of these articels to the wearer and is an important advance in this art.

' Spectacles having arc arms I are most desirable from the standpoint of appearance, as they give the" appear'ance' oi ri-inless 'spectaclesg 'Fheir give this appearance "while pr ovidirig' th'e 'desirfi able supporting featuresfof tlie riinrrld of spectacles; and reduce greatly he tendency to breakage at the strap connections so prevalent-in the older forms of spectacles; While most 'desirable thi form of spectacle is most difiicultto assemble and to adjust to the patients r'equire ments. "While the Opticians ofhigherskilt and better equipment are qualifiecl to a'ssenible and adjust these spectaclesgoptie'ians not having adequate equipment found it most'dinicult 'i'i' notal most'impossible to adjust these spectacles to their patients requirements With the present invention and: the standardization; established by it adjusting is greatly'reduced; fact there is scarcely any adjustment r'equired-f as to the: arc and lens topfeatures and thisspectacle cannow be assembled and adjustedwith. equal facilityon" the old formswith which the Optician is famillar and equipped to handle. The: unusual adjustments have been standardized leaving practically only adjustments to bemade that the optician isrexperienced and equipped to make. i v

.The novel featuresaof the top. edge shaperoil thelenses and the location ofzcthe strap connection substantially on a horizontal linelimfront of. the center of the eyes are of primary/imiportance in. obtaining: the great advantages of this invention; i 1 l Making the? arc arms 'I in a lseries of graded lengths allows them to; be preshaped; The shap.. ing' of the top edges of the lenses'to a former'patterm on a lens edgin'gmachine insuresthatthe top edges will be finished; to: the preshapedelines of the arc arms 1. The standardizatioirzofgthe lens connecting. point, 31' provides an automatic aligning. device: insuring that the preshaped arcs and top edges of the lenses will take their required positions on assembly. i J

.Theframe. parts of the mountingare of' bendable metal and vcomprise'the bridge 2-, the guard arms 4:, the guards- 5; the lens straps 3,, the arc arms 1' and the temples 9. The'pa-rts; are adjusted to the facial requirements of the wearer, by bendi g with pliers the bridge, the guard arm, thearc armsandthe temples. l i

In this invention the: arc arms 1 beingi pre shaped and the top-edgesof thelenses beingpre= determined in th yformer construction, very little if any adjustment of the arcs 1 is required. .It isvery difilcult to bend these arcs 1- without mare ring them and is an operation only the'most expert can accomplish successfully, hence th' preshaping of these parts is important. a i

The process of assembling and adjusting a spectacle to the facial requirements of an individual comprising forming a pair of lenses with upper edge contours of a given shape and at a given distance above a horizontal medial line by forming said upper edge adjacent the vertical center line of the lens to a curve of a radius'whose center lies below and out of the area of the lens and with curvatures on the opposed sides of said vertical center line which are progressively of shorter radii of curvature whosecenters lie within the area of the lens and below said horizontal medial line and terminating in curvatures whose centers lie above the horizontal medial line and blend with the respective side edges of the lenses, forming connection openings on the nasal sides of the lenses on said horizontal medial line, forming connection openings on the temporal sides of the lenses ata given distance above said medial line, forming a lens supporting structure comprising an adjustable bridge member, lens holding means and long and slender temple supports shaped substantially to the upper contour edges of the respective lenses and terminating in temple connection ends having temples secured thereto with said temple .connection ends being located a controlled distance above the horizontal medial line on the temporal sides of the lenses, securing said lens holding meansto the connection openings in the lenses, adjusting the bridge mmeber to position the horizontal medial lines at a given location before the line of straight ahead vision of the individual and to simultaneously position the upper contour edges of the lenses below the brow lines of the individual and adjusting the long and slender'temple supports while retaining the relationof said temple supports with the uppercontour edges of the lenses whereby said long and slender temple supports will follow the upper contour edges of the lenses and the temple supporting ends thereof will be located at a predetermined distance above the horizontal medial lines and to alter the distance between and the angle of the temples relative to the plane of the lenses to meet the facial requirements of the individual whereby the long and slender temple supports will lie below the brow line between the lens and said brow.

10. The process of assembling and adjusting a spectacle to the facial characteristics of an individual comprising forming a pair of lenses each with a connection opening on the nasal side 10- cated'along a horizontal medial line, a connection opening on the temporal side located at a given position above the medial line, and with an upper contour edge located at a given distance above said horizontal medial line, controlling the shape of said upper contour edge by forming a curvature of a radius adjacent the vertical center'line'of the lens having its center below and removed from the area of the lens and blending with curvatures on the opposed sides of the vertical center line having their centers of curvature lying within'the area of and adjacent the bottom ofthe lens and blending with other outer curvatures" of shorter radius lying within the area of the lens with their centers located adjacent to but below the horizontal medial line, said latter curvatures blending with other outer curvatures whose centers lie within the area of the lens above said horizontal medial line, said curvatures of shorter radii blending withthe respective opposed sideedges of the lens, forminga lens supporting structure for said lenses comprising a bridge member, lens holding means, long and slender temple supports initiallyshaped to the same resulant shape of the :upper contour edges of the lenses and. terminating in temple connections to which temples-are pivotally connected; securing the lens holding means to the lenses and the connection openings -therein,5 adjusting the bridge member to position the horizontal medial line of the lenses at a given position relative to the line of straight ahead vision and adjusting the long and slender temple supports While retaining their fitted relation with the upper contour edge of the lenses and the desired position of said temple supports above the horizontal medial line to alter the distance between the temples and. the angle of said temples relative to the plane of the lenses to meet the facial requirements of the individual whereby the controlled distance of the upper contour edges of the lenses above the horizontal me dial line will positionsaid upper contour edges below the brow of the individual and simultaneously position the long and slender temple supports below the brow between the upper contour edges of the lenses and said brow.
